The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to incorrect calculation in the Framebuffer Console (fbcon) in the Linux kernel. A local user can perform a denial of service (DoS) attack.
9) NULL pointer dereference (CVE-ID: CVE-2023-3212)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the gfs2 file system in the Linux kernel. A local user can perform a denial of service (DoS) attack.
10) Race condition (CVE-ID: CVE-2023-35823)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition within the saa7134_finidev() function in drivers/media/pci/saa7134/saa7134-core.c. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.
11) Use-after-free (CVE-ID: CVE-2023-35824)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the dm1105_remove() function in drivers/media/pci/dm1105/dm1105.c. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
12) Race condition (CVE-ID: CVE-2023-35828)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition within the renesas_usb3_remove() function in drivers/usb/gadget/udc/renesas_usb3.c. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.
